Benefits of technology
The system provides convenient, safe, and efficient nitrous oxide administration by minimizing hose length, reducing movement restrictions, enhancing practitioner access and visibility, and preventing excessive gas buildup, thereby improving safety and reducing the risk of system damage.
Problems solved by technology
Originally and until recently the application of these gages was virtually unrestricted and thus the supply system required was relatively unencumbered.
With the advent of mandatory scavenge systems for nitrous delivery, these units became much more bulky and difficult to use in day to day practice and this utilized rate declined.
As illustrated in FIGS. 1-2, current systems running from the control devices to the nasal delivery interface device use multi lumen hose systems which are long, heavy, complex and somewhat stiff.
They pull on the patient's head and limit practitioner accessibility to the patient's mouth area.
As a result they also limit the ability of the practitioner to reposition the patient's head.
In addition, the hose position and length interferes with operator positioning.
This is a dangerous situation because unknown changes occurring in the gaseous anesthetic system can be detrimental to the patient.
Additionally, excess gas expelled into the operatory is harmful to the practitioners.
Also, carts located in the passageways, or workplace around the patient chair, cause inference as the practitioners move around the patient.
Staff can trip over the carts and be injured and the flow of other technology and emergency access is impeded.
As well as the cost of damaging an anesthetic system, rupturing any high pressure, 2000 psi, system can be very dangerous to all occupants of the operatory.
First, current systems usually put the system controls out of direct reach of the medical professional when he / she is seated in normal treatment positions.
This limitation is especially burdensome with wall mounted systems.
This makes it difficult for the medical professional to accomplish anesthetic system adjustments without walking around or reaching around the patient.
This awkward arrangement slows access and response to emergency situations.
Second, current systems often put monitoring device displays and gauges out of direct view of the doctor and assistant.
Currently, there is no known nitrous oxide anesthetic administration system in the prior art which provides these benefits.

Embodiment Construction
[0079]Referring to FIGS. 10-19, a nitrous oxide anesthetic administration system 10 of the present invention is shown. The present invention is a nitrous oxide administration system 10 which provides convenient, direct access by a medical practitioner, a clear line of vision for the medical practitioner, and flexibility to accommodate the patient and medical professional's needs.
[0080]It should be understood that this invention is well suited and preferably used in a dental office environment; however, it may be used in any environment where delivery of objects to a work area is desired. The invention will be disclosed herein in connection with a dental office environment; however, the present invention is not intended to be limited to that particular use and may be used in any health care setting or any setting where a nitrous oxide is required. The configuration of the system components may vary depending on variations in the patient chair, physical site constraints and on the nee...

A system and method for administering nitrous oxide to a patient has a fluid control system that allows a user to monitor and control the supply of gases to a patient. A shutoff valve allows a user to selectively activate the fluid control system. Oxygen flow is adjusted by a flow controlling valve. A differential pressure regulator allows flow of nitrous oxide in response to sufficient oxygen flow. Flow of the nitrous oxide is further controlled by a ratio controlling valve. A display shows the flow of the gases through the fluid control system. A flush valve allows a user to flush the output with oxygen. A flow indicator light may be included. An optional output selector allows the user to direct the flow to one of various output ports. An optional safety scavenge valve prevents operation of the fluid control system when there is insufficient scavenge vacuum pressure.
